LiquaGen Reverse Osmosis Flow Restrictor Capillary Tube Insert - 75GPD for All RO Systems - Ideal for Home Water Filtration and Purification

Works flawless. Just try to remember that you only need to change out your R/O flow restrictor when you are using a different size membrane, from the previously installed membrane. Make sure that it is for the correct "GPD" membrane size. This particular flow restrictor would match up with a 50GPD membrane filter. "Don't mix and match"! Also, if your old flow restrictor is not dirty, then you do not need to change it out during every filter change. As long as it is not clogged or dirty, you should be fine. But there is no law against "preventive maintenance", fight?Not much to say that it works as it should. One thing to note that the packaging did not have any indication as to the flow restrictor capacity and the coloring has been recently changed so I had to contact the seller to confirm that I did indeed receive 50GPD flow restrictor.These are the only kind of flow restrictors I'll use I have several reverse osmosis systems in 3 different family members homes this type of restrictor is the easiest to remove and replace if need beDoes whatvis suppose to do. RO rins well.Works like a Charm and I didn't have to pay an arm and a leg for it !!Easy to install and working perfectly as intended.Really went beyond what I expected! Love iteasy to install 1/4 " line plugs right in
